Why Boeing's Biggest 737 Took 9 Years to Certify

On October 20, 2026 the FAA finally certified the Boeing 737-10, the longest 737 ever built. Boeing launched it at the 2017 Paris Air Show and promised deliveries in 2020. It took nine years. This video walks through the five obstacles that stood between that promise and the certificate: a fuselage so long that its tail risks striking the runway, solved with a landing gear that shrinks as it folds; the two MAX crashes and the 2022 law that changed how cockpit alerts must be certified; an engine anti-ice flaw Boeing had hoped to waive; the Alaska Airlines door plug blowout and the production cap that followed; and the final rounds of flight testing. Then it asks why airlines still ordered more than 1,500 of them, and what the 737-10 means for Boeing against the Airbus A321neo. Figures, dates and quotes come from FAA documents, Boeing statements, the Federal Register, congressional records and reporting from AP, Reuters, CNBC and The Seattle Times, listed in the production source log.
